The coach who has weakened the team would go. I would have a long frank convo with Eric about the way he has accumulated talent. If upon that convo if he can justify some of the drafting and fa pickups and leaving holes in the roster while picking up pieces in areas that had redundancies built in already he can stay. If not he has to go. Now with Eric or his successor the search for a new HC has to start.
Also with the GM that is here going forward a 5 yr plan on how to build the franchise should be made.
That off the top of my head is a really good start.
